Plate tectonics provide the perfect clues to where and what seismic hazard will occur? Discuss. It is at the boundaries of the planet’s tectonic plates that most of the world’s major landforms occur and where earthquakes‚ volcanic and mountain building zones are located. The surface of the planet is made up of seven large and several smaller rigid tectonic plates which float on the semi-molton asthenosphere; the movement of these plates is influenced by the convection cells under the lithosphere

Plate Tectonics‚ Earthquakes‚ and Volcanoes Renee Kuraly 1. There are 13 tectonic plates. (several smaller ones) 2. Evidence for continental drift includes: coastline fit‚ alignment of mountain ranges‚ similar rock sequences‚ fossils‚ modern fauna‚ and ancient climates. 3. We know plate boundaries exist because their defined by earthquake data and the depths of earthquakes show what type of boundary they are. 4. Divergent Boundary- places where plates are moving apart. Convergent Boundary-

The Impact Of Plate Tectonics on the Caribbean * The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. * Volcanic activity in the Caribbean itself‚ as distinct from Central America‚ is largely limited to the eastern Caribbean. Here‚ the Caribbean plate‚ moving approximately west to east‚ meets the North American plate‚ which is moving approximately east to west. This creates what is known as a seductions

Adapted from an activity by Laurel Goodell February 2013 Introduction to Plate Tectonics via Google Earth (24 pts) B. Topographic Patterns Uncheck all of the layers and focus on topographic features of the earth. Topography of the earth ABOVE sea level Questions Answers 1. Are mountains randomly distributed on the continents‚ or do they tend to occur in particular patterns (clusters‚ linear chains‚ arcs‚ etc.)? Some appear in lines and others in arcs 1pt 2. Find Mt.

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

Plate Tectonics & Marine Resources The ocean is one of the worlds greatest natural resources. It provides the Earth’s population with numerous amounts of resources that have value and others that provide pure enjoyment. Transportation is one of the major uses of the ocean‚ along with recreational activities‚ and inspiration. As for resources extracted from the ocean that provide the economy with value‚ three of the main include oil‚ minerals‚ and food. Oil or gas are the top resources extracted

(centered in Nevada this area is about 1500 kilometers wide and runs about 4000 kilometers North/South). Continental crust is thickest beneath mountain ranges and extends into the mantle. Plate Tectonics * The Earth’s surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). * These plates are in constant motion travelling at a few centimetres per year. * The ocean floors are

how you could compare continental drift‚ sea-floor spreading‚ and plate tectonics? Well there are actually plenty of ways to compare these three topics in earth science. You could compare these topics in similarities; continental drift and plate tectonics both start on the same basis of idea‚ that Earth’s lithosphere is made up of tectonic plates. You could also state some differences‚ such as continental drift occurs on all plate types‚ but sea-floor spreading only takes place on oceanic crust‚

Discuss the evidence for tectonic plate movement There has been a variety of different evidence for tectonic plate movement but the main evidence was Wegener’s theory which was based on a variety of different evidence from several sciences. Alfred Lothar Weneger was a German polar researcher‚ geophysicist and meteorologist‚ he first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. In 1912‚ he proposed his explanation – the

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms
